Ultrasound Attenuation in Sr2RuO4: an Angle-Resolved Study of the Superconducting Gap Function
Abstract
We present a study of the electronic ultrasound attenuation α in the unconventional superconductor Sr2RuO4 . The power law behavior of α at temperatures down to Tc/30 clearly indicates the presence of nodes in the gap. In the normal state, we find an enormous anisotropy of α in the basal plane of the tetragonal structure. In the superconducting state, the temperature dependence of α also exhibits significant anisotropy. We discuss these results in relation to possible gap functions.
